This 0.036″-thick stainless steel plate can be mounted to the front of the Zumo chassis to create a slanted, bulldozer-like blade for pushing around objects, such as other mini-sumo robots.
This basic sumo blade (sometimes also called a “scoop”) is intended for use with the Zumo chassis and included as part of the assembled Zumo Robot for Arduino. (Note: It is not the same as the blade included with the newer Zumo 32U4 Robot, and it is not intended for use with this version of the Zumo robot.)
It is made of 0.036″-thick, laser-cut stainless steel, and it ships flat as shown in the product picture. The two tabs must be bent to an angle of approximately 70° before it can be mounted to the front of the Zumo chassis. We recommend using a pair of long-nose pliers to bend the tabs.
